Request body

Responses

200 OK

A JSON object with a list of stations. A station consists of:

  • coordinates
  • name and official ID of the station (the ID is the official Dienststellennummer.)
  • a category of the station, ranging from 1 to 5 (unassigned >= 90). The category depends on the service frequency, the lower, the more frequent.
  • the estimated walkingtime
